Etymology: "Protuberate" comes from Late Latin "protuberō," a compound of the Latin prefix "pro-" meaning "forward" or "out" and "tuber," meaning a swelling or lump. The Latin "tuber" itself referred to a bump or swelling and is also the source of the English word for the edible root, which is named for its knobbly, swollen shape. So the verb essentially describes something pushing out and forming a bump, the same image that gave the potato-like root its name. The word's history is plain: it is a straightforward compound built from two Latin parts rather than a word with a dramatic backstory. Its sense of bulging outward from a surface follows directly from the literal meaning of its components.
